#Heart disease genetics

[swagging-back-to]

it is not controversial to say that if you cannot finacially, emotionally provide for a child and/or your genetics would lead to them suffering then you should not have said child.

guess who has to go 2 cardiology...

[dodgebolts]

actually tho if anyone has good nonfiction book recs I really do want to get back into reading

[uraandri]

my mole is looking kinda weird i'm gonna see if it changes in the next few days and then see a doctor 👍 it could be that my eczema is flairing up right beneath it because the band of my pants goes right over it and it always activates when i'm stressed 👍

Thyroid Awareness Month: Understanding Symptoms and the Need for Treatment

January is observed globally as Thyroid Awareness Month. The thyroid gland is a vital organ in the body that secretes various hormones. These hormones regulate metabolism, energy production, and other essential bodily processes. If left untreated, thyroid-related issues can lead to severe complications.

Common Symptoms of Thyroid Problems

Symptoms of Hyperthyroidism: Excessive sweating Unexplained weight loss Irregular heartbeat Anxiety and sleep disturbances Trembling hands

Symptoms of Hypothyroidism: Weight gain Dry skin Hair loss Persistent fatigue Intolerance to cold Causes of Thyroid Disorders Autoimmune diseases like Graves' Disease or Hashimoto’s Thyroiditis Iodine deficiency Genetic factors Stress and mental pressure Side effects of certain medications Potential Complications of Untreated Thyroid Issues Increased Risk of Heart Disease:

Hyperthyroidism accelerates heart rate, putting extra strain on the heart. Hypothyroidism can raise blood pressure and cholesterol levels. Infertility and Pregnancy-Related Issues:

Thyroid hormone imbalances can impair reproductive health and lead to pregnancy complications. Decline in Mental Health:

Anxiety, depression, and reduced cognitive function are common outcomes. Myxedema:

A severe and life-threatening condition caused by extreme hypothyroidism. Preventing Thyroid Problems and Raising Awareness Maintain a healthy diet (include iodine-rich foods). Get regular health check-ups. Manage stress effectively. Ensure adequate sleep. Consult a doctor promptly if you notice thyroid-related symptoms.

Envisioning a time when people age without fear of dementia

New Post has been published on https://thedigitalinsider.com/envisioning-a-time-when-people-age-without-fear-of-dementia/

Envisioning a time when people age without fear of dementia

The mathematician and computer scientist Richard Hamming once gave a talk about doing great research. “He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important,” Hamming said, emphasizing the importance of open-mindedness and scientific development.

William Li came across this quote as a high school student seeking to dedicate himself to research but unsure how to begin. “I think that science is kind of an opaque area to break into. It’s hard to know what you’re supposed to be doing from time to time,” Li explains.

A double-major in physics and computer science, Li has taken this advice to heart. Keeping his “office door” open has led him to a variety of research projects, from neuroimaging to genomics, that shaped his long-term goal: to become a physician-scientist who moves the needle on Alzheimer’s disease.

Li’s interest in working with patients in a clinical setting was spurred by his grandfather, who was a doctor. In high school, he began volunteering in retirement homes and at the Byrd Alzheimer’s Center and Research Institute at the University of South Florida. Through this work, Li witnessed the devastating effects Alzheimer’s disease has on both those diagnosed and their loved ones.

But that isn’t the only thing about Alzheimer’s that has grabbed his interest. With no cure available, and relatively little known about its cause, the disease is also a compelling scientific problem. “Beyond its human impact, Alzheimer’s represents a frontier of our understanding of human disease,” Li says.

Starting in the fall, Li will begin an MD/PhD program “for the better part of the coming decade.” Following that, he hopes to secure a residency in radiology or neurology, and then to teach and do research while simultaneously practicing medicine. His ultimate goal is a big one — to help develop a cure for Alzheimer’s.

Pursing knowledge

Research has been the highlight of Li’s career at MIT. He says, “To me personally, research means being able to contribute to a body of knowledge built upon by generations of minds in the past. I see modern science and technology as a pinnacle of human achievement, and it’s a dream come true to be able to add to this work.”

In a normal week during the academic semester, Li can spend up to 15 hours in the lab. His research projects have addressed very different topics, but both have guided him toward his current goals.

In the Soljačić and Johnson groups in the Research Laboratory of Electronics, Li he has worked in nanophotonics, a field concerned with controlling light by designing structures the size of a wavelength, for optical and X-ray images, among other applications. 

Li has worked on making X-ray imaging safer and more effective for medical screenings. He also focuses on using computational methods to design nanophotonic device elements for higher-resolution imaging. “Imaging technologies in the future will have pretty enormous applications both for understanding disease and for being able to catch diseases early through diagnosis,” he says.

In his sophomore year, Li began working at the lab of Professor Manolis Kellis at the Broad Institute of MIT and Harvard, using computational tools to study genetic variation among Alzheimer’s patients and how this relates to the disease itself. In this way, the disease can be broken down into subtypes, explains Li, which will make it easier to understand and treat. Last summer, Li won a SuperUROP Outstanding Research Award for this project.

Forging connections

When Li first joined the Kellis lab, the field of genomics seemed vast and overwhelming. To combat this, he started an academic journal club. In the club, Li and his peers would read research papers together and discuss them. In the fashion of a traditional journal club, one person would present at each meeting. Club participants encouraged each other to focus on any research they found exciting, ranging over the past century. As the club has continued, members have started to present their own research to the group as well. “It’s fun seeing what my friends are interested in,” Li says.

Li also served as the collegiate relations co-chair of MIT’s Pre-Medical Society. Here he was responsible for organizing an annual meeting between all pre-med students of the greater Boston area. This mixer was held for pre-med students to other local students and learn from pre-medical advisors and alumni of various Boston schools.

Among the several communities Li is a part of at MIT, his dormitory holds a special place in his heart. Next House, MIT’s largest dorm building, is the place Li has called home since his junior year. Since moving in, he has immersed himself in the living community by assuming roles in several activities hosted by the dorm, such as Thanksgiving dinner.

“I’m very happy to be part of the Next House community. It’s a pretty fantastic place, and I would say that my quality of social life has increased a lot since moving here,” he states.

Along with large events, Li also appreciates the weekly traditions he has created with his Next House friends. Each Sunday, for example, Li joins members of his dorm wing for a 15-minute workout. He says he enjoys exercising in the group setting and frequently attends the gym with his friends, too.

After some downtime on the weekends, Li heads back to the lab and his quest to better understand the brain and how it can be ravaged by dementia. As he continues on his path toward becoming a researcher and physician, he envisions a world where people can age without fear of illness.

This article goes on to say that imply that because Edward IV died aged 43, then death by natural causes is entirely possible and hardly surprising for Henry VI based on his "family background", citing his maternal grandfather's porphyria (which is an entirely speculative diagnosis) and the fact that both parents died before reaching age 35.

I don't think "dysentery caught on campaign + heatstroke" or "childbirth complications" are inheritable conditions. Nor do they really tell us how healthy Henry's parents really were were since these can kill even the most healthy and fit people.

god spare me from articles about Henry VI's death written by Ricardians going, "how do we even know Henry VI was murdered? huh? huh? Tudor propaganda!!"

Do you have a snoot noodle or other variation of sighthound? If yes, there’s new heart health research for the breed happening!

A researcher at Texas A&M whose work I’m familiar with is starting a new study looking at genetic factors contributing to heart disease in Borzoi and related breeds. They just put out a call for dog owners who are willing to submit saliva samples & (noodle) medical records. Studies like this need a big sample size! They’re accepting new sign-ups starting now until March 1, 2025, for dogs both in the US and internationally.

Let’s help make some science!

From the study page:

“Background and purpose

Recent research in Borzoi dogs has revealed that dogs of this breed experience sudden, unexplained death. About 85% of sudden, unexplained deaths in humans are linked to an underlying heart disease. Our existing research in Borzoi dogs has shown that they are predisposed to developing arrhythmias (abnormal heart rhythms) and dilated cardiomyopathy (a heart muscle disease causing dilated heart chambers and weak pumping function).

Due to our documentation of the frequency of these conditions in Borzoi dogs, we seek to identify responsible genetic variations similar to what is seen in humans with electrical cardiac diseases that trigger arrhythmias and dilated cardiomyopathy.

The objective of our study is to identify genetic mutations associated with heart disease in Borzoi dogs and document their existence in other sighthound breeds.

What happens in this study

We are collecting saliva samples from both healthy Borzoi and Borzoi dogs affected with arrhythmias and/or dilated cardiomyopathy. We will also collect saliva samples from any other sighthound breeds.

We will extract DNA from these samples and perform genomic sequencing on a select number while retaining the remainder for further screening.By analyzing the sequencing data, we can compare the genes of healthy and affected Borzoi dogs and identify variants linked to their heart conditions. We will also compare the findings in Borzoi dogs to results from other sighthound breeds.

Pet owner responsibilities

A swab kit will be sent to you for at home use along with a link to an instructional video on how to properly obtain a swab of the mouth. The kit will contain equipment to collect the saliva swab, a history form for your pet, a client consent form and a shipping label to return samples to us.

Participation requirements

To participate, you must have a Borzoi dog or a sighthound breed that is either healthy or affected by arrhythmias and/or dilated cardiomyopathy. Pets may be any age or sex. Electronic or paper veterinary medical records will need to be provided.

Benefits and risks of participating

There is little to no risk for taking a brief swab of the mouth for saliva collection if procedures outlined in the video are followed. No individual genetic test results will be provided to study participants.

Compensation

There is no cost to the owner for participating in this study. No compensation will be provided.”

A brief guide to Testosterone HRT

What is the goal of testosterone therapy?

Testosterone has two main jobs: It causes masculinizing changes to occur throughout the body, and it suppresses the production of estrogen. Some of the changes caused by testosterone are permanent (they would remain if testosterone was stopped), and other changes are reversible.

How is testosterone administered?

Testosterone is available as injections, cream, or gel. Injections are administered either every two weeks intramuscularly (into the muscle) or every week subcutaneously (under the skin). Nursing staff provides injection training here at clinic. Creams and gels are absorbed through the skin and applied daily.

What are the irreversible effects of testosterone?

Testosterone causes voice deepening, clitoral growth, body/facial hair growth, and sometimes male-pattern balding (also influenced by age and genetics). Testosterone may irreversibly affect fertility. Desires for fertility should be considered prior to starting hormones, and for those seeking fertility preservation (or education about fertility preservation), referrals can be made to Lurie’s fertility preservation team.

What are some of the reversible effects of testosterone?

Testosterone causes increased muscle tone, fat redistribution (hips to stomach area), skin oiliness and acne. Mood changes (often irritability, having a “shorter fuse”) and heightened sex drive may occur. Menstrual cycles will change and eventually stop after some time. There may be genital changes caused by low estrogen levels.

What are some of the known side effects and risks of testosterone?

Testosterone may increase your metabolic risk profile — that is, the risk for conditions such as heart disease, diabetes, high cholesterol or blood pressure. The risk for heart disease is higher for people who smoke cigarettes, are overweight or have a family history of heart disease.

Testosterone causes hematocrit, the proportion of red blood cells in a volume of blood, to increase. This blood thickening, at high levels, can be life-threatening, causing stroke or a heart attack.

Testosterone can also cause increased appetite, headaches, and acne.

A low-detail diagram of the upper half of three bodies is displayed. From left to right, the bodies represent having been on testosterone for little to no time (a month or less), a medium amount of time (six to eight months) and a greater amount of time (a year or more).

The diagram is a visual representation of testosterone effects on the body. Hip mass shifts to the stomach area, The adam’s apple grows. Muscle mass grows and shoulders become broader. Facial and body hair grows on the arms, face, and assumably the legs not displayed in the image. The skin gets oily and acne appears on the face.

Testosterone affects: skin, muscle mass, body fat, body hair, voice change.

Increased skin oiliness and acne starts within 1-6 months of testosterone. Its complete effect can be within 1-2 years.

Increased muscle mass and strength starts within 6-12 months of testosterone. Its complete effect can be within 2-5 years. This effect is highly dependent on the amount of exercise one does.

Voice pitch deepening starts within 6-12 months of testosterone. Its complete effect can be within 1-2 years.

Body fat redistribution starts within 3-6 months of testosterone. Its complete effect can be within 2-5 years.

Facial and body hair growth starts within 6-12 months of testosterone. Its complete effect can be within 3-5 years.

Monthly periods stop within 2-6 months of testosterone.

Clitoral enlargement of 0.5 inches to 1 inch begins within 3-6 months of testosterone. Its complete effect can be within 1-2 years.

Male pattern hair loss starts when you have been on testosterone for over a year. Its complete effect date is variable. It depends on age and genetics, and can be minimal.

Sex drive also increases.

How do we monitor for safety?

Labs (bloodwork) are collected prior to starting hormones and every three months for the first year of treatment. In the second year, labs are checked every six months. Tests that are monitored include cholesterol, liver tests, hematocrit, and hormone levels. These labs can be drawn at Lurie’s or a local facility.

How quickly will changes develop?

Remember, it’s normal to want to see changes occur rapidly, but (just like in puberty) these changes take time! Most changes start to begin around 3-6 months after starting testosterone and take years to fully develop.

Will I look like my friend _____?

Remember, everyone experiences puberty differently. Factors other than testosterone (such as genes!) affect appearance. It’s impossible to predict exactly what changes will develop.

It’s important to take the prescribed dose of testosterone. Taking more increases health risks.

Always tell your health care provider if you have questions or concerns about your health.

This is Eman a Biotechnologist from Gaza. Asking for help is not easy. It's not easy at all. You have no idea how mentally and emotionally tiring this is. But when thinking that the price is my family's life, getting out of here safely and achieve my doctoral degree dream, it just pushes me more and more to do this until we reach our goal. I'm here as I try to reach out to more people asking for their help to support our family's campaign so we can survive while all you have to do is literally donating even by just the price of your morning coffee or maybe a simple breakfast, So I think I'm not asking for so much. We're really tired of living under these catastrophic conditions for a whole 10 months. Your generosity will not only change our lives but also remind us that even in our darkest hour, we are not alone. https://gofund.me/d597b8e2

Hi there, Eman. I'm a biotechnologist just like you. I looked up your work and saw your research on identifying genetic risk factors for ischemic heart disease and celiac disease. That's really admirable work, and I hope you can one day achieve your dream of studying for your PhD in Malaysia. For now, I've donated what I can to try and keep you and your family safe.
